Study: Electrons are Really, Really Spherical
To put that in context; if an electron was the size of the solar system, it would be out from being perfectly round by less than the width of a human hair.
To determine the roundness of electrons, scientists observed the subatomic particles with lasers, looking for any wobbling as the electrons spun. The degree of the wobble would indicate the degree to which electrons were not spherical. No wobbling was observed, forcing the researchers to conclude that as far as their instruments were concerned, electrons are perfect spheres.
Of course, no scientist can ever be satisfied, and the team is planning on backing up their research with new experiments derived from recent work done with antimatter. In forthcoming experiments, molecules will chilled to extremely low temperatures in order to greater control the movement of electrons. Hopefully, the team can take even more accurate measurements and add a few more zeros behind that decimal point.
